[PATCH v2 00/23] Use asm-generic for mmu_context no-op functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It would be nice to be able to modify mmu_context functions or add a
hook without updating all architectures, many of which will be no-ops.

The motivation for this series is a change to lazy mmu handling, but
this series stands on its own as a good cleanup whether or not we end
up making that change.

Arnd, is this something you could take through your asm-generic tree?
(assuming arch maintainers are okay with it)

Thanks,
Nick

Since v1:
- Added acks and feedback from various people.
- Fixed a nommu build error caught by ktp.
- Dropped unicore32.
